did it for fun...but when i revved i noticed the fuel spraying upwards...is this good? bad? or does it matter? can i really expect that much better response? thanks. runnin stock d15b2...soon to have a a6 head.. and another question. can i just drop the si head on? or is the timing diff between b2 bottom and a6 head? will my belt and stock a6 cam shaft work?

 

the only time you get a gain from this is if your tb is broken

 

ok thanks...wasnt quite sure how much the air flow would improve...i'll just leave it on then. i guess its there for a reason

 

Don't bother doing that. You will end up thinking you have 10 extra whp and try racing other kids on the streets.

 

do the mpfi swap.
